Chapter 1
To understand human processes we need:
Physics, chemistry, biology, and psychology
Imprinting
Lock and Key analogy
The key can also be called social releaser
and can be very specific Ex. the
characteristics of an objects head.

SOCIAL RELATIONS
Chapter 11
- Perceptual qualities related to behaviour and appearance of others
- Implicit processes fact, automatic
- Absorb social norms and use them to our advantage
Social brain hypothesis
Primates and humans differ from other species

Early Humans
early humans lived in groups: hunters and
gatherers *
gathering very important because hunting
was only 20% successful
looked much like us division of labour females caring for infants and gathering,
males - hunting and gathering
humans DID i

described by formal parameters

Sexuality
Gender
study
70% of males would go home with a female
who said theyre attractive
NO females would go home with male
Humans are almost the only species that
has sex face to face (bonobos also do)
Darwin Sexual
Selection
Competition males compete

Chapter13
Health
Senescene term for aging
Genetics of those who live past 70 are more similar than
younger people (30)
Natural selection diminishes with age
Diseases exist because pathogens also evolve
Pathogens: a bacterium, virus, or other microorganism

Chapter 9: Sexual Selection
Back to Darwin
Runaway sexual selection: female is more willing to mate with a male w/ a certain trait, trait will
be passed on
Sexual selection involves 2 processes:
- Same sex competition most obvious in males
- Selection of

Chapter 10: Kin and Family Relationships
Structure of Relationships
Kin classification involves:
genealogical distance: tells us who we are related to and what this allows/prohibits us to do
with said indiv
social rank: hierarchies and when theyre importa

Homosexuality: Recessive
Gene?
Weve already shown that there isnt a gene that codes
for homosexuality
It simply would not have been passed on
What if we assume that there is a recessive gene
responsible?
